Esophageal Cancer

WHAT IS ESOPHAGEAL CANCER?

Esophageal cancer begins in the esophagus. Esophageal cancer embodies two distinct histopathologic types, squamous cell carcinoma and adenocarcinoma. If the cancer spreads outside the esophagus, it often goes to the lymph nodes first then spread to almost any other part of the body. Esophageal cancer is more common in men than in women.

RISK FACTORS OF ESOPHAGEAL CANCER

Tobacco and alcohol use are considered the major contributing factors in the development of esophageal cancer worldwide. Low socioeconomic status as defined by income, education, or occupation is associated with increased risk for esophageal cancer. Increased body mass index is a risk factor. Gastroesophageal reflux disease has been implicated as one of the strongest risk factors.

SYMPTOMS OF ESOPHAGEAL CANCER

The most common symptoms are dysphagia (difficulty in swallowing) and weight loss.
